About Coolant Reservoir

The coolant reservoir is very important as it has the job of making sure that the plastic container holds the coolant fluid. The purpose for that is to control the excess coolant fluid which is important for the cooling system in the vehicle.

Coolant reservoir

The reservoir is vital to the cooling system since its main function is to keep the coolant fluid until it is needed. The reservoir can be found by following the hose from the radiator and it can vary from vehicle as well. It is also where the coolant goes into the system and does not go straight into the radiator.

The procedure for the reservoir is to allow a little bit of coolant to release in order to relieve pressure. And the rest of the coolant stays in the system to create a pressure that circulates the coolant.

Common issues with a bad coolant reservoir

A bad coolant reservoir can lead to coolant levels being empty, leaks, and the engine may overheat on the driver when not in good conditions.
